hi bherulaal,The primary role of lipids in your body is to provide energy for muscles and body processes. Fat is energy dense, containing 9 calories per gram, whereas protein and carbohydrate contain only 4 calories per gram. About half of the fuel your body needs when at rest or during everyday activity comes from lipids.not only that they function in many ways, in hormonal transport, provide insulation to your body etc.hope this helps, good luck

Hi Bherulaal Bhramaniya

Lipids are fats. In the body they take the form of phospholipids, cholesterol and fatty acids. Although fats play a role in obesity and disease, your body needs a certain amount of fat to function -- also known as essential body fat. Men need at least 3 percent body fat and women need at least 12 percent body fat to ensure normal functioning. You get triglycerides and phospholipids from your diet, and you get cholesterol from your diet and your body also produces it naturally. The role that lipids play depends on the type of lipid.

Lipids, also known as fats, play many important roles in our body, from providing energy to producing hormones. You wouldn't be able to digest and absorb food properly without lipids. Of course, eating more fat than you need can lead to weight gain, but in proper amounts lipids are a healthy part of your diet.
